Image captioning is a technology that automatically generates descriptive text for images. It combines techniques from computer vision and natural language processing to analyze the content of an image and produce a relevant caption. This process helps in making images more accessible and searchable. The applications of image captioning are vast, including enhancing social media posts, improving image search engines, and assisting visually impaired individuals by providing context to images. By understanding the elements within an image, this technology can create meaningful descriptions that convey the essence of the visual content.
